I hvae in mind that your system is working, because you said that finished configurate java...., with commands.
yuou used equo, in theis is is not a good practice to use meerge now, but you mmay tri remove java with equo oe espritz, and then,re install Java with emerge and changing the FLAGS fot obtain support for 686 architeture...
but the message that you ask, in their first post, for me, not indicates any problem, simply informyou that some plugins of the Java are not known for your architeture, indicating fo r me that some multi architeture versions works....!
an example, my DX2 Duo Core is a AMD 64 machine, is a 686 architeture, and when i install the sun java... ( becuase i use the messenger mercury, that is sun Java dependent), i received teh same message, i dont farid for it, in only belongs for me that "parts " of the Java are multi hardware architeture, Java is still working in my comp, since without Java, Mercury not works, and is working!
